Sorry about the previous wrong example. For GAWK the format is a little
bit different than the AWK format. Here is the GAWK format:



gawk -F":" '{if($1 == ZZ) { print $6 }}' -v "ZZ=${username}" passwd.bak
>output



If needed two arguments passed in you would have to give another -v
preceeding the double-quote surrounded variable and it's value, ie.,
"YY=12345" , ie. :



gawk -F":" '{if($1 == ZZ) { print $6 } ; if(YY == $4) { print $6 }}' -v
"ZZ=${username}" -v "YY=12345" passwd.bak >output



You may want to put the script into a file (say filename "space.gwk"
) and try it like the below:



gawk -F":" -f space.gwk -v "ZZ=${username}" passwd.bak >output

Or might try this one:



awk -F":" '{if($1 == ZZ){print $6}}' ZZ=${username}
passwd.bak >output

I'm not sure, but
it looks like the apostrophies get in the way.
try:
awk -f":" '/'$username'/ { print $6 }' passwd.bak >output

I hope that works.
